This really didn't feel like a series finale to me, but maybe that's just because I'm not ready for this show to end.
Started this based on a rec from a friend. In middle of season 2 with the episode with the Foo Fighters reference
I've been re-reading the series on my daily commute. I just finished the 2nd. I forgot how devastating the ending was to me, maybe even more than Ember’s Tomb in the 1st book.
